I am living a similar situation and ran across your post when googling Narcissism and Dementia. It is a living hell and I've been blessed with respite care to get out of the house a few hours. Yet that was becoming "not enough" as there were all the hours I had to stay cooped up with my spouse. I find it challenging bc the behaviors are narcissistic and at the same time dementia plays into it. My spouse fell and broke his leg a couple of weeks ago and has been in the hospital and just yesterday moved to long term care. While there has been stress involved in getting all the care coordinated with insurance and placement, at least when I come home, it's quiet, I can think, I don't walk on eggshells, I can get things done around the house that have needed attention for sometime. My home feels safe. Something I've not felt here for years now. (It's hard to feel safe emotoinally/mentally when living with a narcissistic person.). While the intention is to have my spouse's leg heal, have PT/OT and then come home, he will be there for the next several weeks. I'm not sure what will take place in the long run. Right now, my spouse is very angry with me and has tried manipulating his way home for days. He has called family members and a pastor we once had in an effort to get someone to bring him home. He is in complete denial about the severity of his broken leg and about his dementia. It's useless to explain or argue with a brick wall. If you can, you may want to start looking into assisted living or whatever community care this person needs. I know this can be scary as many of us rely on our narcissistic/dementia spouse for the income. Yet your health and sanity are just as important. Try to find a support group where people who've walked this path can offer direction and sources as well as validate your situation. I didn't realize I was depressed. I was just pushing through each day until all this happened. Now that I can breathe, I see how all this has impacted me over the last few years.
